I agree with this, but i'm not sure that the code really ends up being
that large.

Another concern of mine is that it's possible to end up needing _both_
kernel support (to set media type) and user-land support (to configure
other EEPROM bits, like I/O port addresses, on cards that support

Wasting space in the kernel is annoying, but wasting it in the kernel
when you need a special user-land program anyway is especially
